Fiber Input Interface
BM110 is suitable for most industrial fiber lasers. It is equipped with collimating lens assembly.
The connection between the end of the fiber and the cutting head is called fiber interface.
Commonly used fiber connectors include QBH, QD and so on, and every fiber interface has its
unique fixation method. Please refer to corresponding instruction of fiber interface.
Note:
The optical devices must be kept clean and all dust must be removed before use. If
the optical fiber is vertically inserted in the laser head, the laser head must be rotated 90
degrees to the horizontal level and then inserted the optical fiber in it to prevent dust
from entering the interface and falling on the surface of the lens. Insert the optical fiber before
fixing the laser head.

Fiber Insertion and Interface Direction Adjustment
In this section, an optical fiber insertion method is described in conjunction with QBH connector.
First, align the red point at the end of the QBH connector with the red point of the handwheel; then
remove QBH dust proof cover, the red mark of fiber output end is aligned to QBH red mark, insert
the fiber interface straight to bottom; Then turn the QBH handwheel clockwise. It is in place when
you hear the "Da" sound, then pull the handwheel up and turn clockwise again.
